Question

I tried adding a custom method to the Node class but ended up creating a new class that holds a node object in a variable.

so the question is. is it even possible?

I did this:

public class Trip implements org.w3c.dom.Node { 
    [...generated methods...] 
    public String myMethod(){
        return "";
    }
}

but I was getting lots of errors so I ended up doing this

public class Trip { 
    private Node mNode;
    public void Trip(Node tripNode){
            this.mNode = tripNode;
    }
    public String myMethod(){
        return "";
    }
}

Answer 1

org.w3c.dom.Node is an interface, therefore your posted code won’t work.

You don’t want to start trying to implement your own DOM, so I suggest you think of a different approach. What is it you want to do?

You might be able to make use of get and setUserData to accomplish your goal.
